Hi LiamHing,

Operating system Disks are not being shipped any more with the computer because, the systems are shipped with a program to create the Recovery Disks.

Refer the following link which has steps on Using the Dell Backup and Recovery Manager:

You may also try factory reset on the computer. Refer the following link for more information:

Windows 7 factory reset: http://dell.to/11AZoyY

Kindly private message me the service tag of the computer so that I can take this case further. To private message the service tag click my User name and click Start conversation.

Awaiting your response!

I'm becoming really peed off with Dell, I spent £1000 on a computer that doesn't come with simple restore discs.   My X51 decided to turn my whole disc in to a dynamic disc and wiping it in the process, now I have no OS.   How am I supposed to install OEM OS without discs? I'm really annoyed.   I now have an expensive doorstop!    Best part is I was told by Alienware twitter support to run software on a PC without an OS, what a frickin genus!    Please help me!

As my partner states, we are no longer sending discs with the new orders. Did you manage to fix the issue with those suggestions?
